ア１９となり空調装置１に戻る。 Further, this discharged air 2 flows through the ceiling duct main body 9, and at the same time descends through the small duct 11 from the upper gap A of the partition plate 10, passes through the continuous slit 12, and is dispersed left and right by the wind guide 13, and becomes the ceiling discharged air. 1
4 is released over the entire length of the cabin, and returns to the air conditioner 1 as return air 19.
なお、この天井吐出し風１４は立席乗客の頭に
直接当らないように、風案内１３の曲線部により
天井下面の遠方へ拡散される構造としてある。 The ceiling discharge air 14 is configured to be diffused far away from the lower surface of the ceiling by the curved portion of the wind guide 13 so as not to directly hit the heads of standing passengers.
天井吐出し風速の均一化を図るために、仕切板

るものである。 In order to equalize the ceiling discharge air velocity, the upper gap A is adjusted by the air volume adjusting member 15 at the upper end of the partition plate 10.
has been adjusted. This processing dimension is determined based on data confirmed by preliminary confirmation tests, and the data is shown in FIG. A is a shape with parallel dimensions A, b is a dimension A with the tip enlarged, and c is a dimension A with a tapered shape.As shown in the right half of Figure 5, the shape of c is optimal for wind speed. I understand that. Therefore, the ceiling duct gap size of the present invention is processed into the shape of c to supply the ceiling discharge air 14.
なお、この風量調整部材１５は天井ダクト本体
９の内壁との間隙を先細りとするよう高さを変え

を介して取付けられるため作業が容易である。 According to this embodiment, by providing a partition plate in the ceiling duct body, the small duct is divided and formed, a tapered gap can be formed between the partition plate and the inner wall of the ceiling duct body, and the opening of the small duct is The entire ceiling duct can be configured by installing a wind guide that covers the entire ceiling. Therefore, there is no need to provide a special member for obtaining a uniform wind speed distribution, and the configuration is simple. Furthermore, since the gap between the air volume adjustment part of the partition plate and the inner wall of the ceiling duct body is tapered, the temperature distribution in the cabin can be evened out. Further, the air volume adjusting section of the partition plate can be easily worked by simply changing its height continuously, and the work is easy because it is attached via a spacing member.
